Missing most of the prime line with PC-GF

I have been printing with Tinmorry PC-GF and the prints have been coming out pretty good, but it is not printing the first 80% of the prime line at the beginning of the print. When I watch the nozzle it doesn’t start extruding until the last 8-10mm of the prime line.

Any ideas on what settings may be causing this, or if it is even a concern? I haven’t seen this with any other filaments.
